Unity + AR = .exe

Hi everyone,
I'm realy sorry for my english, i'm so bad (i'm french), google translate help me ...
I am currently beginning of the course of the first year of BTS and the task entrusted to me at the moment is the following : Find a new Library , a new plugin for Unity in order to get out of Augmented Reality applications en.exe (hence the name of strangeness topic) .

Originally , the company in which I am using to develop Vuforia for Android and iOS , and was very happy. Vuforia not to get Windows applications, they need a new tool as their needs have changed. I do not seek a special kind thing with face tracking and all, I just want a proper tool with Image Recognition, Detection Tracking, and multidetection , Multitracking compatible with Unity , they worship. At the moment, I 've already tried :

- ARToolkit : this is a good tool but the free version does not have the Windows app and the paid version through the ARmedia ® players and boss, that, it would not .

- NyARToolkit : a homolog of ARToolkit free which allows for the Windows app with Unity in Free Version . I hit it a little with the colleague who needs , concerns, the trick is wrong masturbated , ladders are made a bit anyhow , their marker is really strange and the doc on the net or on the codes is half translated from Japanese. ( I keep it if I find anything else and it is not gaiety of heart ... ) .

- ARPA Plugin for Unity : the stuff is not bad at all, the problem: The free version is that when we do tests, it cut every 2 minutes and must be restarted , so the team of the company, this is not. The paid Pro version , it is not a good idea , it just takes 6 months to create Windows , it is quite expensive . This is not too.

- Metaio SDK Unity : I 'm testing it right now , it looks very complete air is damn good . The paid version is too expensive for the box in which I am, so I 'm testing with watermark free version.

I would be very grateful! I would complete the As my quest, but I first wanted to get your opinion as soon as possible to be active soon .
I also inform you that I 'm not good with all these tools and computers in general , even if I can get help to side, trying to keep it simple as far as possible, I would be very grateful!
I hope you have something to help me.
On a good day !
